According to an almanac, 80% of adult smokers started smoking before turning 18 years old. (a) If 100 adult smokers are randomly selected, how many would we expect to have started smoking before turning 18 years old? (b) Would it be unusual to observe 85 smokers who started smoking before turning 18 years old in a random sample of 100 adult smokers? Why? (a) We would expect about adult smokers to have started smoking before turning 18 years old. (Type a whole number.) (b) Would it be unusual to observe 85 smokers who started smoking before turning 18 years old in a random sample of 100 adult smokers? O A. No, because 85 is less than u - 2o. O B. Yes, because 85 is between u- 20 and u+ 20. OC. No, because 85 is between u - 20 and u + 20. O D. Yes, because 85 is between µ-20 and u +20. O E. Yes, because 85 is greater than u+ 20.

Concept explainers

Angles in Circles

Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.

Arcs in Circles

A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

(a) We would expect about adult smokers to have started smoking before turning 18 years old.
(Type a whole number.)
(b) Would it be unusual to observe 85 smokers who started smoking before turning 18 years old in a random sample of 100 adult smokers?
O A. No, because 85 is less than u - 20.
O B. Yes, because 85 is between u – 20 and u + 20.
O C. No, because 85 is between u- 20 and u +20.
O D. Yes, because 85 is between u - 20 and u + 20.
O E. Yes, because 85 is greater than u + 20.
